Strict Testing & Quality Assurance
Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:
Complete communication & CAN-bus verification
Sensor input/output and signal integrity checks
Injector & ignition pulse simulation
Power, ground, and load-circuit analysis
Flash memory integrity and checksum validation
Thermal and voltage-stress testing to confirm reliability

Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

It feels great to have my truck running like new again without dealing with dealership hassles.

I was a bit nervous about ordering an ECM for my 2020 Tundra, but this unit arrived quickly and was already programmed to my VIN, which saved me a ton of hassle. Installation was straightforward—just unplug the old one and plug this right in without needing any extra tools or software. Once hooked up, the truck fired right up and runs just like it did before. It’s clear this is a quality part, and the support team was really helpful when I had a couple questions before buying. Definitely a smooth experience from start to finish, and my Tundra feels good as new.
